LIP-TURNING MACHINE.

Specification of Letters Patent.

Patented May 21, 1907.

Application filed June 29, 1906. Serial No. 323,992.

To and] w/wm/ it may concern..-

Be it known that I, GEORGE A. HURLEY, of Rockland, county of Plymouth, State of Massachusetts, have invented an Improvement .in Lip-'lurning Machines, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

In the lip turning machine, known as the Goodyear lip turning machine, for turning back the lip of the Goodyear welt insole, the insole is fed forward by a pair of positively driven feed wheels. The upper feed wheel is formed with a thin beveled edge I which enters the channel slit and by bottoming in said slit serves to guide the work along. In order that the feed wheel may enter the channel slit, its edge is made very thin, al most sharp, with a tendency by wear to be come thinner and sharper, and when bottoming in the slit it is crowded with considerable pressure against the bottom of. the lip.

It sometimes happens, particularly with poor, thin or flabby stock, that the lip is cut or otherwise injured by the pressure of the beveled edged. feed wheel upon it and the insole is spoiled or is left with a weakness at a point where it should be very strong,

This invention has for its object to provide this machine with an edge guide, adapted to engage the edge of the insole for the purpose of guiding it, so that the beveled edged feed wheel is no longer required to serve as the guide for the insole, and hence need not bottom in the channel slit.

Figure 1 shows in side elevation a lip turning machine having an edge guide embodying this invention. Fig. 2 is a front view of a portion of the machine. Fig. 3 is a detail of the edge guide. Fig. 4 is a detail showing the assembled parts in their relative p0sitions in connection with an insole.

Referring to the drawings (t represents the rotating circular table upon which the insole is laid, it being arranged to rotate in a hori zontal plane, and b the rotating bevelededged feedwheel which is made as a thin flat disk, located beside the table and extends over the table for a short distance, and supported on an inclined shaft. Said feedvheel and table, cooperate to feed the insole along. 0 and d represent the lip-turning devices. These parts are common in the Good year lip turning machine, to which my improvement is applied, hence a more com plete description is necessary.

The edge-guide consists of a horizontally disposed. finger 6, having a curved engagingface, which is adapted to engage the edge of the insole, and also having a downwardly extended ear e at one end by which it is se cured to a pivot-shaft 6 said shaft being horizontally disposed and having its bearings in an arm 6 which is rigidly secured to the frame of the machine. The pivotshaft is located between the inclined shaft bearing the feed-wheel, and the vertical shaft bearing the table, but is arranged quite close to said inclined shaft, and the ear e projects upwardly and supports the guiding-finger 6 below the beveled-edged feed-wheel and just back of its engaging-portion, so that when moved it will engage the edge of the insole, when the latter is placed upon the table and the table is elevated so that the insole is held pressed firmly into engagement with said feed-wheel, and will hold the insole with its lip free from engagement with the edge of the feed-wheel. An arm 6 is secured to the pivot-shaft 6 which extends forward, at right angles to the ear e.

The arm 6 is pivotally connected to the upper end of a rod 6 which extends downward through a hole a in the base-plate e and is connected at its lower end to a treadle 2..

Depression of the treadle moves the rod 6 downward and turns the pivot-shaft and moves the edge-guide in a direction radial to the axis of the feed-wheel, toward and into engagement with the edge of the insole.

The rod 6 has a screw-threaded portion intermediate its length, as at a", and at "a point thereon, above the base-plate c, has upon it a nut 6 arranged to strike the baseplate when the treadle is depressed, to thereby limit the downward movement of the treadle and consequently limit the move ment of the edge-guide in a direction toward the insole.

A fiat spring e is attached to the underside of the base-plate, or it may be otherwise supported, which engages a nut or finger on the rod or bar 6 the purpose of which is to lift the treadle and consequently remove the edge-guide from the work.

The position of the edge-guide will be controlled by the treadle, although its movement in a direction toward the work is limited.

By the employment of an edge-guide in combination with the rotating table and the rotating thin flat beveled-edged feed-wheel, constructed substantially as herein shown and described, I am enabled to feed and guide the insole and also to hold the insole with its lip free from engagement with the feed-wheel, and as a result the lip of an insole composed of poor, thin or flabby stock may be turned up and will not be cut or otherwise injured. Furthermore the extent of turning up the lip may be regulated, that is to say, it

need not be turned up abruptly from its junction to the sole and in such case a welt, slightly narrower than usual, may be em ployed, as for instance, in practice a welt of an inch narrower will suffice.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. In a lip turning machine, the combination of lip-turning devices, a work-supporting table rotating in a horizontal plane, a thin flat feed-wheel having a beveled edge, mounted on an aXis, inclined relatively to the axis of the table, so that its engagingface, which extends over the table, is parallel with the face of the table, an edge-guide located beneath the feed-wheel, between its inclined shaft and the edge of the table, and

- means for moving it in a direction radial to the aXis of said feedwheel, to guide the work and to hold it with its lip free from engagement with the edge of the feed-wheel, substantially as described. v

2,. In a lip turning machine, the combination oflip-turning devices, a work-supporting table rotating in a horizontal plane, a thin flat feed-wheel having a beveled edge, mounted on a shaft inclined with respect to the shaft bearing said table, a horizontal pivotshaft, an ear secured thereto, a guidingfinger extending inwardly from said ear, which is located beneath the feed-wheel and between its shaft and the edge of the table, andmeans for rocking said shaft to move the guiding-finger in a direction radial to the axis of the feed-wheel, substantially as described.

3. In a lip turning machine, the combination of lip-turning devices, a work-supporting table rotating in a horizontal plane, a thin flat feed-wheel having its edge extended over the table, means for rotating said feedwheel and an edge-guide located beneath said feed-wheel for guiding the work and for holding it with its lip free from engagement with the edge of said feed-wheel, substantially as described.

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
